Worthless from a security standpoint, because the screenshots can still be taken from a desktop or laptop device.

You can always steal something if it can be seen. I think it's more of to clearly express that they don't want you to screenshot whatever it is. You can subvert it but you know you're doing something you shouldn't.

I don't use AirBnB so I can't actually think why you'd want to disable screenshots in certain places. I'm curious now though, can someone tell me?

I would assume two reasons: 1) Don't let people easily scrape their content and list it on a competitor. 2) Make it hard to people to put up fake listings that look real with the intention of scamming users.
